Abstract:
Objective To study the efficacy of thyroidal arterial embolization in treating hyperthyroidism by using different embolizing materials and the relationship between recurrence rate and the numbers of embolized arteries. Methods 56 cases with hyperthyroidism were divided into group A (25 cases) and group B (31 cases). Patients of group A had their thyroidal arteries embolized with gelfoam particles and stainless coils after arterial infusion of a total dosage of 24 mg of blemycin. Patients of group B had their thyroidal arteries occluded with polyvinyl alcohol (PVA) particles. The effectiveness and general complications of arterial embolization for these two groups were compared and the relationship between recurrence rate of hyperthyroidism after treatment and numbers of embolized thyroidal arteries was studied. Results It showed effectiveness in all patients within 2 3 months. The follow up records showed, the recurrence rate of hyperthyroidism was 28% and 16.1% for group A and group B respectively but without statistical difference. The recurrence rates were 46.7% for those patients with 2 thyroid arteries embolized and 12.2% for those with 3 4 arteries embolized, showing significant difference ( ? 2=7.751, P
